SPECIFICATION forming part of Letters Patent No. 793,833, dated July 1, 1905.

Application filed June 8,1904. Serial No. 211,708.

To aZZ 2071 0121, it may concern/.-

lBe it known that l, Jenn H. GAULT, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Insulating Handle Connections, of which the following is a full, clear, and exact description, reference being had to the accon'lpanying drawings, which form a part of this specification.

My invention relates to an insulator for handles of vessels used to hold hot liquids adapted to be inserted in the handle between the grasping portion thereof and the body of the vessel.

The object of the invention is to secure a more certain and effective union between the insulator and the adjacent handle-section or between the sections of the handle separated by the insulator than has been heretofore possible.

' in the accompal'iying drawings, Figure 1 is a side view of acoflee-pot with the insulator applied to the handle thereof. Fig. 2 is an enlarged sectional view on line 2 2 of Fig. 1. Fig. 3 is a section on the line 3 3 of Fig. 2. Fig. T is a section on the line a 4: of Fig. 2. Fig. 5 is a section on the line 5 5 of Fig. 2.

Referring first to Fig. l, a is a vessel shown here as a coffee-pot. o and c are end sections of the handle, projecting, respectively, from the upper and lower portions of the body of the vessel. (.5 is the grasping portion of the handle connecting the end sections 6 and o and forming with the latter the handle as a The insulating devices 0 e are inserted, respectively, between sections Z) and (Z and between sections (1 and (Z. These two insulating devices are the same in construction, and the description of one will serve as a description for the other.

Referring now to 2, 3, 4, and 5, f and g are the core members of insulating material. They may be made integral, although it will be more convenient from a manufacturing standpoint to make them separate, as shown. The portion f of the core has a convex periphery and extends outwardly beyond the portlon The grasping portion mi of the handle is secured to the core in the manner shown in the patent gran ted to me November 24:, 1903, No. 7eii,Tel-3 --that is, a metal shell having a convex body h and a cylindrical neck or head 1 is secured to the core by bonding or spinning the body /1. around the core member f, while the head 1 projects above the core. The body of the shell is somewhat shorter than the core member f, so as to leave a definite space between the lower end of the shell-body and the core member The head v extends and closely lits within the hollow lower end of the grasping portion (Z of the handle and is brazed, soldered, or otherwise secured thereto. Z* is a metal ring embracing the core member 1 and firmly secured thereto by the following means: The lower end of the ring upset to form an anm'dar internal flange which penetrates the core member. The upper end of the ring is upset similarly to the lower end, forming an annular internal lian m, which penetrates or overlies the core 11161111301. Between its upper and lower ends a groove n is formed around the ring, which displaces the metal of the ring inwardly, forming an an n ular internal bead 0, which somewhat CllSlTdLCQE-B the material of the core member and prevents any movement longitinlinally of the ring thereon. Also between the upper and lower ends of the ring or Sp are formed on the ring by displacing inwardly the metal thereof and the ears inserted into the core member, as may be best seen in 41:. A rivet (1 extends from one. side of the ring to the other, extending through the core member, the heads of the rivets resting in countersinks in the ring. By the foregoiugi'neans the ring Z: and the core member (7 are [irmly secured together. Of course it will be understood that all of the described means of union need not be employed, the employment of any one or more of them being within the scope of my invention, which, in fact, may exist independently of the particular securing means enmloyed. The ring Z= extends and closely fits within the hollow end of the lower luuidlo-section c and is brazed, soldered, or otlmrwisc secured thereto. if the core 1nembersfg are made integral, the structure as far as described may be considered a complete structin'c so far as concerns its operativeness; but if the core members are made separate it is necessary to provide some means for uniting them. Moreover, whether the core members are separate or integral it is advisable to provide means for rigidifying them. The rivets '2 '7', which extend through both core members and whose heads rest in countersinks in the upper surface of core member f and the lower surface of core member g, perform this rigidifying function whether the core members be separate or integral and also where the core members are originally separate serve to unite the core members together into a unitary core. It is also advisable for further security to unite the ring 7r to the core member f. This is accomplished by the following means: An annular disk or flange .5- is secured by brazing, soldering, or other means to the top of ring it, or it may be made integral with the ring It by lengthening the latter and at its upper portion bending the ring inwardly to form the flange m, as before described, and thence outwardly to form the flange s. The flange 8 extends outwardly beyond the ring and beyond the end of the handle-section 0. t tare rivets extending through the flange a and core member f, thereby binding the core member f to the ring 717 and aifording, in fact, an additional or alternative means of securing together the core members f and g and of rigidifying the core by reason of the attachment of the ring it to the core member g. It will be observed that there is a space between the rim of flange s and the lower end of the body it of the shell it This discontinuity in the metal prevents the conduct of any heat from the body of the vessel to the grasping portion of the handle. The substantial length of contact between the handle-section 0 and the ring l: enables-a very firm union to be effected be tween the same.

Having now fully described my invention, what I claim, and desire to protect by Letters Patent, is-

l. An insulating handle connection, comprising hollow handle-sections, a core of insulating material, means whereby one portion of the core may be secured to one section of the handle, a ring embracing the other portion of the core and extending within and secured to the other section of the handle, means securing said ring to the last-named portion of the core, and independent means engaging both portions of the core for rigidifying the same.
